51550886 divided by 993 
Let's see how many times 993 fits into 51550886.

On to step 1:
The number 993 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 993

Going ahead to step 2:
If we divide 51 by 993, we get 0 and a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Take the next digit (5) from the dividend and append it to 51, then repeat: 515 / 993

Moving on to step 3:
993 goes into 515 0 times with a remainder of 515.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 515, we end up with 515.
Fetch the next digit (5) from the dividend, attach it to 515 and continue: 5155 / 993

On to step 4:
993 goes into 5155 5 times with a remainder of 190.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 190 after subtracting 4965 from 5155.
Bring next digit (0) of the dividend behind the 190 and repeat the process: 1900 / 993

Going ahead to step 5:
When dividing 1900 by 993, we get 1 with a remainder of 907.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
Subtracting 993 from 1900 leaves us with 907.
Take the next digit (8) from the dividend and append it to 907, then repeat: 9078 / 993

Moving on to step 6:
The number 993 fits into 9078 9 times, leaving a remainder of 141.
Use 9 as the next digit of our solution. 
Result so far: 519.0
If we take 8937 away from 9078, we end up with 141.
Take the next digit (8) from the dividend and append it to 141, then repeat: 1418 / 993

Step 7:
993 can be fit into 1418 1 times, resulting in a remainder of 425.
The number 1 becomes the next digit in our result. 
Result so far: 5191.0
Subtracting 993 from 1418 leaves us with 425.
Include the next digit (6) from the dividend after 425, then repeat: 4256 / 993

Going ahead to step 8:
The number 993 fits into 4256 4 times, leaving a remainder of 284.
Record the quotient 4 as the next digit in the result. 
Result so far: 51914.0
Deduct 3972 from 4256 and we're left with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

On to step 9:
When dividing 2840 by 993, we get 2 with a remainder of 854.
Put 2 as the next digit of the answer. 
Result so far: 51914.2
Subtracting 1986 from 2840 leaves us with 854.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8540, and continue the process.

Let's proceed to step 10:
When dividing 8540 by 993, we get 8 with a remainder of 596.
Record the quotient 8 as the next digit in the result. 
Result so far: 51914.28
Subtract 7944 from 8540 to get 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Step 11:
When dividing 5960 by 993, we get 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 51914.286
If we subtract 5958 from 5960, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 12:
When dividing 20 by 993, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 51914.286
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 13:
The number 993 fits into 200 0 times, leaving a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 51914.286
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final outcome is 51914.286, with a leftover of 0.0002.
